id: PYSEC-2021-2
details: Improper Access Control on Configurations Endpoint for the Stable API of
  Apache Airflow allows users with Viewer or User role to get Airflow Configurations
  including sensitive information even when `[webserver] expose_config` is set to
  `False` in `airflow.cfg`. This allowed a privilege escalation attack. This issue
  affects Apache Airflow 2.0.0.
